Confluence change IP Address of VM

[Mikhail Shitikov]

Hello.

I have installed Confluence 6.5 on a Linux Centos 7 and this works with external DB PostgreSQL 9.6. This VM's get IP addresses via DHCP.

I have changes in my network and my Confluence and DB gets new IP addresses, so, it's doesn't work now :( If I choose old addresses it's works fine.

So, when I try open my confluence via new IP, for example 10.11.1.4:8090

FYI: Confluence VM is available with new IP by ICMP and SSH, just don't opening in  web browser.

Page doesn't open, after few minutes I've got this error:

HTTP Status 500 - Could not open Hibernate Session for transaction; nested exception is net.sf.hibernate.exception.GenericJDBCException: Unable to acquire JDBC Connection.

Sometimes, I remember, I have found good instruction at support.atlassian.com, but now they are changed design and I can't found this manual :( it's not friendly design now.  

People, please, help me fix this issue or help me find this manual :)

Thanx
